Climatic Signals from Intra-annual Density Fluctuation Frequency in Mediterranean Pines at a Regional Scale
Tree rings provide information about the climatic conditions during the growing season by recording them in different anatomical features, such as intra-annual density fluctuations (IADFs). IADFs are intra-annual changes of wood density appearing as latewood-like cells within earlywood, or earlywood-like cells within latewood. The occurrence of IADFs is dependent on the age and size of the tree...
متن کاملGenetic Control of Growth, Wood Density and Stem Characteristics of Pinus pinaster in Portugal
A Pinus pinaster Ait. progeny trial involving 46 open pollinated families was established at two locations in Portugal (Leiria and Escaroupim). Height, diameter, Pilodyn and stem characteristics (straightness, branch size and number of whorls) were assessed at age 5 and 12 and were used to estimate variance components, heritability, phenotypic and genetic correlations between traits. Estimates ...
متن کاملMolecular proxies for climate maladaptation in a long-lived tree (Pinus pinaster Aiton, Pinaceae).
Understanding adaptive genetic responses to climate change is a main challenge for preserving biological diversity. Successful predictive models for climate-driven range shifts of species depend on the integration of information on adaptation, including that derived from genomic studies. Long-lived forest trees can experience substantial environmental change across generations, which results in...
متن کاملIndividualistic and Time-Varying Tree-Ring Growth to Climate Sensitivity
The development of dendrochronological time series in order to analyze climate-growth relationships usually involves first a rigorous selection of trees and then the computation of the mean tree-growth measurement series. This study suggests a change in the perspective, passing from an analysis of climate-growth relationships that typically focuses on the mean response of a species to investiga...
متن کاملResponses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
